The effectiveness of removal of nitrogen oxides in tobacco smoke main stream by porphyrin and ferripor-phyrin were determined by muriatic acid naphthaline-ethylene diamine spectrophotometry. Results The contents of nitrogen oxides in tobacco smoke main stream decreased with the increases of the contents of porphyrin and ferripor-phyrin added into the cigarette filters (porphyrin: r= -0.9943, P
